Performance Testing
Performance testing is a testing practice performed to
determine how a system performs in terms of
responsiveness and stability under a particular workload.
It can also serve to investigate, measure, validate or verify
other quality attributes of the system, such as scalability,
reliability and resource usage.
https://en.wikipedia.org/wiki/Software_performance_testing

4. Performance Load Testing with Tsung
Goal
- Demonstrate the system meets performance criteria.
- It can compare two systems to find which performs better.
- It can measure which parts of the system or workload
cause the system to perform badly (Bottleneck).

17. Performance Load Testing with Tsung
2. Identify Performance Acceptance Criteria
- Throughput
- Response Time
- Resource utilization
For example
Website must handles 100 concurrents and each request
must respond within 300ms and cpu utilize must not higher
than 85%

3. Plan and Design Tests
- Scenarios
- Test Data
- Clean Data
- Collect data to analyze
